Description
Not to be claimed with prenatal/fetal assessment

Explanation

Updated October 26, 2026

L8 means this service can't be claimed with a prenatal or fetal assessment.

What it means

L8 means the laboratory service is not payable when claimed together with a prenatal or fetal assessment for the same patient.

How to fix it

  1. Check which prenatal or fetal assessment was billed for the patient.
  2. If you believe the decision is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details.

Don't resubmit if

  • The line is already on your RA. Question it with an RAI, not a new claim.
